我有一本笔记本（HP EliteBook 8460p）内置HP hs2340 HSPA+ 移动宽带模块（爱立信 F5521gw- 我在 WWAN 硬件加密狗上找到的标签）...
从第一天开始宽带模块就没有真正工作过，但我不需要它，所以没关系……有时（但很少）未选中的选项“手机宽带“出现在（网络管理器）面板中。
我正在使用带有 3.2 内核的 ubuntu precise，现在我更新到 lts-trusty 3.13 内核，没有任何变化（就这个主题而言）。
这个问题和答案似乎有关联，但是没有作用。
我发现的唯一可能与我的宽带模块相关的内容是以下几行/lib/udev/rules.d/77-mm-ericsson-mbm.rules：
# HP hs2340 Mobile Broadband Module
ATTRS{idVendor}=="03f0", ATTRS{idProduct}=="3a1d", ENV{ID_MM_ERICSSON_MBM}="1"
顺便说一句：也lsusb没有列出 WWAN 加密狗......
更新：
今天模块运行没有任何问题，所以我运行了一些命令来收集尽可能多的信息......不知道是否有帮助......

答案1
WTF...! 现在我得到了 (非常简单的) 答案：
--> 我将其发布在这里并且不会删除该问题（尽管这可能有点令人尴尬），因为我搜索了半个网络却没有找到答案或只是找到正确方向的提示！
昨天我又谈到了这个话题，一开始移动宽带还能用，但过了一会儿就不行了……过了一段时间我注意到，在我把电池插入电池仓后，它又能用了！-就是这样！！！
将电池插入电池仓后，WWAN 加密狗就可以正常工作，没有电池就不行了。
所以我最终打电话给 HP 支持部门，询问电池和不稳定的 WWAN 加密狗出了什么问题（以确定是否是连接松动）！
他们回答说，根据设计，（原装）电池必须放在其托架中才能与 WWAN 加密狗建立连接，即使电池因短路而损坏也是如此！
我无法相信这真的是必要的，因为 SIM 卡放在一个很好的按压插槽中（电池后面），而适配器/天线本身放在笔记本电脑的另一侧。
另外，我有点失望，因为一直插入电池会缩短它的寿命...！:-/
总结：
它是一个与硬件相关的“连接”东西...插入电池（并将其留在托架中）就这样。
有人使用过这种 WWAN 加密狗连接吗……？ - 有没有办法让它在不需要一直给电池通电的情况下工作？
